Sažetak
In this paper the authors conducted a numerical investigation of residual stress distribution on two butt-welded plates. Subsequently, they incorporated the obtained residual stresses into a welded model that included a hypothetical semielliptic crack. The stress intensity factors (SIFs) were calculated using the eXtended Finite Element Method (X-FEM). The obtained SIFs results match very well with the analytical results of the API 579-1 standard with the biggest difference being 6.73%. Similar differences can be noticed in the comparison between X-FEM and the results obtained by the conventional Finite Element Method (FEM), where the biggest difference between these two results is 6.75%.
